- Extent loss on this day 102k, 8 k more than the average loss on this day (of the last 10 years) of 94k,
- Extent loss from maximum on this date is 6,499 k, which is 276 k, 4.1% less than the 10 year average of 6,774 k.

- Extent is at position #11 in the 44 year satellite record

_____________________________________________
On average 67.7% of extent losses from maximum to minimum done, and on average 59 days to minimum

Projections. (Table JAXA-Arc1)

Average remaining extent loss (of the last 10 years) would produce a minimum in September 2022 of 4.66 million km2, 1.48 million km2 above the Sept 2012 record low minimum of 3.18 million km2, and 13th lowest in the satellite record

From NSIDC Data - some graphs

Russian Shore to 80 North

Kara - average melt,

Laptev - slow melt,

ESS - very very slow melt,

Chukchi - average melt

From NSIDC Data - 2 more Area graphs

Atlantic Front
Greenland Sea - a head of average sea ice area loss
Central Arctic - how much area loss is retreat of ice edge from 80 North and how much is melt ponding & low concentration?

Last Ice Area
Beaufort - sea ice area at an extreme high.
CAA - impact of very high temperatures not showing so much in sea ice area data.

interstitial · « **Reply #554 on:** July 19, 2022, 05:19:25 AM »

The pause in the CAA looks shorter with no reversal. That would indicate some impact IMO even if it is not very dramatic.

(For other folks mesmerized by watching ice melt)
Eyeball estimates from Gero's JAXA 10 year average Extent loss per day trendline:

Peak rate at just a bit less than 100K per day ~ca. July 8
75% of peak rate begins/ends ~ca. June 20, August 5
50% of peak rate begins/ends ~ca. June 15, August 24.

From NSIDC 5-Day Trailing Average sea ice area data

The low concentration ice in the Central Arctic seems to now be affecting NSIDC area data. Sea ice area in the Central Arctic now 3rd lowest in the 44 year satellite record despite below average overall Arctic sea ice area losses.

From NSIDC Data

Sea ice area and extent, especially in the High Arctic, well above the 2010's average.

From NSIDC Data - High Arctic Sea Ice Area Graphs - 1 of 2

Kara - looks like it will melt out as usual
Laptev - sea ice area still well above 2010's average
ESS - with sea ice area well above the 2000's average, surely too late for anything like a complete melt.
Chukchi - complete melt still possible.

Beaufort - with sea ice area well above the 2000's average, surely too late for anything like a complete melt.
CAA - very unpredictable as depends on melt and any ice import from the centre.
Central Arctic -still waiting for the Big Blob of low concentration ice to translate into open water and for the Atlantic Front to move the ice edge towrads 85 North

It's getting later and later in the melting season
